Only 2nd gear
 

I have a 92 3/4 ton with a 518 trans. I stopped at a stoplight and the truck only has 2nd gear going forward, reverse works fine. The fluid don't smell burnt. I'm going to drop the pan and change the filter but, could the shift seliniod be bad? I am also check for error codes in the ECM. Thanks

i dont think youll get any codes im pretty sure the trans isnt computerized enough to throw one.

what is the make and model? if it wont shift into any other gear except 2nd gear and reverese then i would check the 12v power going to the trans computer maybe 2nd is it's default gear

It's a 92 dodge 4X2. Where would the trans computer be at. or is it the 2 wires going into the side of the trans, not the backup switch.

make sure you dont use a test light. only a digital multi meter will do for computerized systems. make sure you have ground as well.

The tranny should work fine in 1st 2nd and 3rd with no 12v to it. It just wont have OD.

So am I looking at the possibility of it being the shifter solenoid?

i would say your looking at a rebuilt transmission most likely

I downloaded the ATSG service manual from a different thread and it said that 1-3 gears are hydraulically controled and overdrive is controled by the solenoid.

yeah thats what we keep tryin to tell u. there are prob some spools stickin in the valve body. most likely has got some dirt in it. hopefuly u didnt smoke the whole thing already.

sry i forgot what thread this was under. the 12v thing wont work. my bad

I'm taking it in to the trans shop. If it needs it the rebuild is $1800.

any issues with it's performance before now?

When the truck was cold it would start driving slow. the engine performace was ok but the trans had no pickup. Once it was warmed up it was alright.

My truck should be done today. The guy on the phone said that when they started to put it back together that the transmission governor was bad. I'll find out more when I go to pick it up later today.

It took them longer than they thought to take care of the speed governer. One of the bolds on the governor loosened up and came out. When it did it wiped out the parts inside the governor and put a hole in one of the oil tubes. It's nice to have my truck back. Too bad it took almost 2 weeks but they had a hard time finding the right gov.
